Best radiant barrier insulation cuts energy use, reduces utility bills

Wednesday, March 16, 2011 by Universal Forest Products

By installing the best radiant barrier foil insulation, such as Enerflex, you can reflect up to 96% of the radiant heat energy from the sun back through your roof. As a result, your attic space is up to 30° cooler, which leads to a more comfortable and consistent temperature throughout your home as well as energy savings.

Radiant Barrier / Reflective Insulation Reduces the Workload on Your AC UnitU.S. Department of Energy - Reflective Insulation

This increased performance of your insulation and duct work, and decreased workload on your air conditioner and other appliances means Enerflex reflective insulation will pay for itself in utility bill savings in a relatively short period of time.

Here are three tips for reducing the workload on your AC unit:

  1. Turn ceiling fans on to recirculate hot air that rises and get cold air off the ground
  2. Install a programmable thermostat and have it set to turn on only when you're home
  3. Change your furnace filter every three months or before it gets too dirty

Simply download the Enerflex Tax Credit Certificate for your tax records to save 10% up to $500.

Safe and Sustainable
Enerflex will not harm your shingles. A normal radiant barrier may raise the temperature of your shingles 2-5 degrees and will not affect the life or warranty of your shingles. Enerflex can help you qualify for 5 LEED points under EA1 and MR5, is an ENERGY STAR rated product and has a Class-A fire rating.

I'm looking into using Enerflex, but I was also interested in spray foam insulation. Would it give me any benifit to cut and staple the reflective material flat against the roof deck, and then spray the foam over it to just add to the insulation properties?

Sam, thanks for your question. For best results, I recommend applying the spray foam insulation directly to the roof sheathing (underside of the roof) between the joists then apply Enerflex radiant barrier foil (rolled or panel product) over the insulation.

To be most effective, the radiant barrier needs to be facing an open air space.
